Be itknown that I, LEoPoLnLANGE, a citizen of the United States of America, residing at Chicago; in the county of Cook and State of Illmo1s, have discovered a newand useful "Process for Recovering Spirits from Internally- Charred Liquor-Casks lVhich Have Been Once Used.

It has been well'known for some time that such casks after use contain a quantity of spirits-which is contained in the cells of the arregl interior. Various methods have I been attempted .to recover the cellularly contamed spirits-from such charred casks.

plish this urpose in a simple, effective and economlca manner. o

To this end, my invention consists in the novel process herein set forth and explained an more. particularly pointed outin .the

- In carrying out my process, first charge 1 ample,

'- for a perlo dition of the cask, at intervals agitating the said empty casks with a small quantity of water, preferably from two to fiveallons,

and close the cask, thereafter agitatmg the .water by movement of the cask, such, for exas rolling, 'u ending'or otherwise, so that the contame water will thoroughly saturate the interior of the cask. After this is done, I (permit the charged cask to stand of time, depending upon the concontents as before; I have secured very gpod results by letting the charged cask stand a period of time, approximately, 72 hours, a itating the same at intervals as stated. 11 freshly emptied casks however,

this time may be shortened considerably.

After letting the casks stand as stated, I then draw oil the contents and re-distil the same in the Well known manner to, recover the s irits. This pro'cedure,.I usually continuea p urality of times generally running from 3 to 5, according to the condition of the cask, and

I find that by this process, substantially all of the contained spirits is recovered, the total amount recovered sometimes equaling nearly a gallon to a cask and seldom running below one-half gallon. I y

A larger quantity of water may be satisfactorily employed, with the single excelp e tion, that by thus increasing the-bulk, t

expense of re-distilling is correspondingly increased, therefore, I find it more satisfactory and more economical to use a comparatively generate steam I also do not find the result as satlsfactory, the expense necessary to mainta n such a' temperature generally incured t e' bestresults by 'mafintaininga tem peratffine of thewater at from to degrees Fahrenheit. The object of my invention is to aceo 7 My understanding of the process is, that thanthe spirits, and aided by a well known afiinity of alcohol'for water, seeks out the elpirits in the cells of the charred interior and the spirits commingling with the contained water in the cask.
